ClosureFactoryIteratorAggregate

Class ClosureFactoryIteratorAggregate.

Provides an iterator implementation based on a closure factory.

This class allows dynamic generation of iterators using a provided closure. It is particularly useful in scenarios where deferred computation or dynamic iterable generation is needed.

Usage Examples:

Using Generator Function:

---

• Full name: \FastForward\Iterator\ClosureFactoryIteratorAggregate
• Parent class: \FastForward\Iterator\CountableIteratorAggregate

Methods

__construct

Initializes the ClosureFactoryIteratorAggregate with a closure.

public __construct(\Closure $factory): mixed

Parameters:

Parameter	Type	Description
$factory	\Closure	a function that returns an iterable structure

---

getIterator

Retrieves the iterator generated by the factory closure.

public getIterator(): \Traversable

This method invokes the provided closure and returns the resulting Traversable instance. Important: If the generator contains a return statement, its return value will not be iterated.

Return Value:

the iterator generated by the factory function

---

Inherited methods

count

Counts the number of elements in the iterable.

public count(): int

If the inner iterator implements Countable, it uses that. Otherwise, it counts the elements by iterating through them.

Return Value:

the number of elements in the iterable
